PATENT BOTTLE-NECK-FORMING MACHINE.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed October 30,1905. Serial No. 285,003.

To all whom, it may concern:

Be it known that I, JAMES C. HENDERSON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Bottle- Neck-Forming Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a device for forming the necks of protective bottles that is to say, my invention relates to a device for forming the necks of those .bottles known as bottle-breakable necks; and my invention has for its object to provide a device of this class which will quickly and effectually formthe neck of a bottle after the bottle has been blown and while the glass is yet in a plastic condition, so that the neck of the bottle can be broken along certain grooves, which breaking is necessary in order to withdraw the cork from the bottle, and my invention is particularly designed to form the neck of a bottle such as is set forth in my copending application.

WVith this object in view my invention con sists in the novel construction for cutting or forming the grooves in the bottle-neck; and my invention also consists in the construction for forming a tang or shoulder within the bottle-neck, which tang or shoulder prevents the cork from being withdrawn in the usual way; and my invention also consists in the construction employed for holding or supporting the neck of the bottle while the same is being cut or grooved; and my invention also consists in certain novel features of construction and in combinations of parts, which will be first fully described and afterward specifically pointed out in the appended claims.

IVhile there are a great number of bottles known as bottles breakable necks, I have by exhaustive experiments found out that a great number of these devices cannot be manufactured, owing to the peculiar constructions of a great many of the necks and owing to the length of time which would be required to form some of the necks. Generally speaking, a breakable-neck bottle has been of no commercial value because of the fact that the cost of manufacturing is so great that the bottle could not be made to compete with the ordinary class of bottles, and it matters not how much protection a bottle affords the user unless said bottle can be manufactured at a low cost and, at most, at a very slight advance over the cost of an ordinary bottle, the bottle is of no commercial value, as the cost of the same precludes the use of the bottle. It is for the purpose, therefore, of providing a machine for quickly forming the necks of breakable bottles that I have made my present invention, and with my machine an ordinary bottle can be formed into a breakable-neck bottle in a very short period of time and at an immaterial advance in the cost of the bottle.

Referring to the accompanying drawings, which illustrate my invention, Figure 1 is a perspective view of the machine in an operative position. Fig. 2 is a front elevation of the same, illustrating the machine in position for receiving a bottle-neck. Fig. 3 is a rear elevation of the same. Fig. 4 is a similar view showing the position of machine when forming a bottle-neck. Fig. 5 is a front elevation, partly in section, showing bottleneck in section in machine. Fig. 6 is a horizontal section taken through the double camplate and forming-jaws. Fig. 7 is a perspective view of one of the neck-cutting knives. Fig. 8 is a vertical longitudinal section through the machine, showing bottleneck in section. Fig. 9 is a perspective view of the bottleneck mandrel, showing same in position of forming the bottle-neck. Fig. 10

is a vertical transverse section taken on line 10 10' of Fig. 9. Fig. 11 is a perspective view showing mandrel in position for withdrawing the bottle-neck therefrom, and Fig. 12 is a vertical transverse sectional view taken on line 12 12 of Fig. 11.

Like numerals of reference indicate the same parts throughout the several figures, in which 1 indicates the machine, which comprises the face-plate 2, which is secured in position on a wall or support by means of screws 3.

4 indicates the supporting-post, which is preferably threaded into the face-plate 2, as shown in Fig. 8. The outer end of the post 4 is reduced, as shown at 5, Fig. 8, so as to accommodate the forming-jaws 6 and 7, which are carried on said post, a nut 8 being provided to hold said jaws in place.

IIO

9 indicates the bottle support or guide, which comprises the angle-plate 10, having its end 11 slotted at 12, so as to make the same vertically adjustable on the post 4, and 13 indicates a preferably semicircular rest, which is adjustably secured on the plate by means of the set-screw 14.

15 indicates the bottle-neck mandrel, which, as shown in Fig. 8, is preferably threaded into the'face-plate 2. Said mandrel is formed hollow and carries within the same a longitudinal-moving rod 16, to which rod is secured an operating-handle 17, said handle entering the mandrel through a slot 18, which slot 18 extends longitudinally of the mandrel, the slot 19 transverse of the mandrel connecting with said slot 18, as clearly shown in Figs. 9 and 11. to the outer end of the longitudinal-moving rod 16 within the mandrel is the tapered portion 20, and, as shown in Figs. 9 and 11, said tapered portion 20 is provided with a wide longitudmal groove 21, and said tapered portion is also provided with a longitudinallyextending lug 22, which enters a corresponding aperture 23 in the mandrel. As shown in Fig. 9, a groove or depression 24 in the periphery of the mandrel is provided just in rear of the lug 22 on the tapered portion of the mandrel, and when the mandrel is in position shown in Fig. 9 the inner end of the lug 22 forms a wall 25, as shown in Figs. 9 and 10.

A coil-spring 26 is arranged within the mandrel between the post 27 of the-handle 17 and the wall 28 within mandrel, said spring being of the compression type and normally tending to hold the tapered portion 21 in position shown in Figs. 8 and 9.

29 indicates the double cam-plate, which, as shown in Figs. 3 and 4, is provided with two oppositely-located curved slots 30, and 31 indicates two stud-screws, preferably threaded into the rear face of the formingjaws 6 and 7, said stud-screws passing through the slots in the double cam-plate 29, as shown in Figs. 3, 4, and 6. Secured on the periphery of the double cam-plate 29 is a handle 32, by means of which the said I double cam-plate 29 is rotated. A circular opening 33 is formed in the center of said double cam-plate 29, and said cam-plate is passedover the mandrel 15, as shown in Fig.

. 8, said cam-plate being held in this position by means of the stud-screws 31 in the forming-jaws 6 and 7.

Referring particularly to the forming-j aws 6 and 7, it will be seen from Fig. 2 that each of the forming-j aws are provided with a semicircular depression 34 in the contiguous edges of the said forming-j aws 6 and 7 in such manner that when the two forming-jaws 6 and 7 are brought together a circular opening 35 is formed, as shown in Fig. 1 and also in Fig. 5. Referring to Fig. 6, it will be seen that two transverse grooves 36 are formed in the form- Connected ing-jaws 6 and 7, and referring to Fig. 2 it will be seen that a small convex extension 37 is riveted on the forming-j aw 7. Referring now to Fig. 7, it is seen that the forming or cutting knives 38 and 39 are formed preferably integral, the knife 38 being formed on an are taken on the circular opening 35 formed by the forming-jaws 6 and 7, the said knife 38 being substantially a quarter of the circle, and it will be seen from Figs. 2 and 7 that the knife-plate 40 is provided with two slots 41, so as to make same adjustable on the face of the forming-j aws 6 and 7. When the knife plate 40 is secured in position on the face of the forming-j aws, the transverse knife 39 lies in the transverse groove 36 in the formingjaws, said knife 39 being illustrated in section in Fig. 5.

Having thus described the several parts of my invention, its operation is as follows: After the bottle has been blown and while yet in a plastic condition the bottle is placed in the rest 13, which rest 13 is adjusted so as to bring the neck of the bottle in line with the mandrel 15. The operating-handle 32 on the double cam-plate 29 is moved into position shown in Fig. 3, which causes the studscrews 31 to travel to the outer ends of the curved slots 30 in said double camplate, which forces the forming-jaws 6 and 7 apart or into position shown in Fig. 2. When the forming-jaws are in this position, the neck of the bottle is passed over the end of the mandrel until the said neck comes in contact with the shoulder 42of the mandrel The operating-handle 32 on the double cam-plate 29 is then moved into position shown in Fig. 4, which causes the said screws 31 to move to the inner ends of the curved slots 30 in the double cam-plate 29, which draws the forming-jaws 6 and 7 together into position shown in Figs. 1 and 5. As the forming-jaws come together the curved knife 38 and the longitudinal knife 39 engages the bottle-neck and cuts two longitudinal grooves and a semicircular groove in the bottleneck, the depth of said grooves being controlled by the adjustment of the kiife-plate 40. As said grooves are being cut in the neck of the bottle the convex extension 37 on the forming-jaw 7 engages the neck of the bottle and forces the glass down into the groove 24, Fig. 9, in the mandrel, as shown in Figs. 5 and 8. The double cam-plate is then rotated, so as to open the forming-jaws 6 and 7, and the handle 17, which moves the longitudinal rod 16 within the mandrel and the tapered end portion of the mandrel, is pulled forward to the end of the slot 18, Figs. 9 and 11, and then moved transversely into the slot 19 and into position shown in Fig. 11. The forward movement of the handle 17 carries the lug 22 of the tapered end portion 2O out of the corresponding depression 23 in the mandrel, and the transverse movement of the handle 27.

ICC

rotates the tapered end portion 20 until the groove 21 therein is in line with the groove 24 in the mandrel. The purpose of this construction is as follo ws: When the glass of the bottle-neck is forced by the extension 37 on the forming-j aw 7 into the groove 24 in the mandrel, a shoulder is formed on the inside of the bottle-neck, as shown in Fig. 8, or the surface on the inside of the bottleneck is otherwise altered or interrupted, according to the form or character of the mandrel, and in order to withdraw the bottle-neck from the mandrel provision must be made for allowing said shoulder clearance, so as not to injure the form of the shoulder. Unless such provision is made the bottle-neck could not be withdrawn from the mandrel after the shoulder is formed thereon, as of course is obvious. Consequently by the construction shown and just described the rotation of the tapered end portion 20 of the mandrel brings the groove 21 in line with the groove 24 and moves the wall 25 on the lug 22 out of engagement with the shoulder formed on the inside of the bottle-neck and allows said shoulder to pass freely off the mandrel. After the bottle has been formed and withdrawn from the mandrel the handle 17, which controls the tapered end portion 20 of the mandrel, is moved transversely to the end of the slot 19, and the coil-spring 26 within the mandrel carries the tapered end portion 20 back into position shown in Fig. 9. The forming-jaws 6 and 7 being open during the operation of withdrawing the bottle from the mandrel, the machine is now ready to receive and form another bottle-neck, which is passed over the mandrel, and the operation just described is repeated. In order to form a bottle-neck as described, only a very small period of time is consumed, as in operating the machine one hand is employed to operate the handle 17 of the mandrel and the other hand rotates the double cam-plate 29 by means of the operating-handle 82, so that the bottle-necks can be formed just as quick as they can be placed on the mandrel and the two operating-handles manipulated in the manner described.

Having thus fully described my invention, I do not wish to be understood as limiting myself to the exact construction herein set forth, as various slight changes may be made therein which would fall within the limit and scope of my invention, and I consider myself clearly entitled to all such changes and modifications.

- What I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. A machine for forming the necks of protective bottles, comprising a mandrel for supporting the neck of the bottle, hinged members having means thereon for engaging the outside of the neck of the bottle to alter or interrupt the surface on the outside of the neck of the bottle and a double cam-plate connected to hinged members for operating the same, substantially as described.

2. A machine for forming the necks of protective bottles, comprising a mandrel for supporting the neck of the bottle, movable members connected to each other and provided with means for engaging the outside of the bottle-neck to alter or interrupt the surface on the outside of the bottle-neck and a rotatable cam-plate connected to said movable members for operating the same, substantially as described.
